GAS-PRODUCER.

Specification of Letters Patent.

Application filed December 14, 1914. Serial No. 877,004.

To all whom it may concern:

Be it known that I, EBENEZER A. W. Jur- FERIES, a citizen of the United States, residing at \Vorcester, in the county of VVorcester and Commonwealth of Massachusetts, have invented a new and useful.Improvement in Gas-Producers, of which the following, taken in connection with the accompanying drawings, in a specification.

The present invention relates to gas producers, and has particular reference to the disposition andsupport of the main shell, or fuel containing section, of devices of this class.

The developments of gas producer practice have led to the use'of spreading and leveling devices for the surface of the bed of fuel; a highly efficient method of securing the desired spreading and leveling action contemplates relative rotation between the body of fuel and the spreading device, whereby the latter is rendered effective with respect to all portions of the surface of said bed.

Another step in the development of gas producers resides in the automatic discharge of the ashes therefrom, and a preferred em- 'bodiment of apparatus for accomplishing this function provides a substantially radial plow or scraper carried within the ash supporting section of the producer and having a. sweeping action with respect to the contents of the same when relative rotation between said plow and ash support is produced, thereby crowding the ashes outwardly and'delivering the same from the edge of said support.

The present invention provides a constructionpeculiarly adapted for the attainment of both of the above enumerated mechanical operations in a gas producer. The,

The numeral 1 indicates the lower portion of a gas producing chamber, inclosed within a wall or shell 2 which constitutes the fuel supporting section of the producer. The lower end of said shell, in accordance with approved practice, opens into a concentric ash support or pan 3 having a horizontal bottom 4:, and flaring walls 5, which surround, and are spaced from the wall of shell 2.

In the attainment of the desired relative rotation between fuel bed and leveling member in the one case, and between ash support and ash plow in the other case, it will be apparent that the simplification of the mechanism for imparting, such relative rotation between the several parts, in the manner previously set forth, can be best served by the rotation of the ash support 3 and fuel section 2 in unison. Under these conditions, the leveling member 6, shown conventionally in Fig. 1, may be suspended or otherwise supported from the stationary cover section, not shown, of the producer, for the support of which the standards 7 are employed. The ash plow 8, pivoted concentrically with respect to the ash support 3, and normally rotating in unison therewith by reason of its contact with the bottom 4, is designed to have its rotation interrupted at intervals, when it is desired to efiect a discharge of ashes over the wall 5, as will be clearly understood. However, the operation of the plow 8 requires its sweeping and crowding action to'be eflective over the entire bottom surface of the ash support from center to periphery, and furthermore, the interposition of a stationary stop in the path of plow 8, designed to interrupt its rotation and bring about the desired discharge of ashes, necessitates the preservation of a wholly free and continuous space between the wall 5 of the ash support and the shell 2, as will be apparent. Hence. the

rotation of the ash support 3 and shell 2 in unison demands a means of connection between the two parts which will not obstruct the sweep of the plow 8, nor interfere with the intermittent interruption of the rotation of said plow.

In carrying out my invention, the ash support 3 is disposed for rotative movement upon a plurality of rollers 9. Any 105 bottom 4 is formed with a concentric pas- 110 desired action of the ash plow 8 mitted to be carried out under the most sage 12, which communicates in any suitable manner with a blast passage 13, opening upwardly through the supporting floor of the producer. forming a continuation of the passage 12, is secured upon the upper side of the bottom 4, and communicates with and provides for the support of a hollow spider casting 15, herein shown as having three hollow radial arms 16,16, 16, which serve for the distribution of the blast to the superposed bed of fuel.

The spider 15 preferably has a central aperture, not shown, with respect to which a spaced circular cap 17 is effective in providing for an annular upwardly directed jet tion, as. .shown in Fig. 1, providing an an-" nular base portion 22 which seats upon the projections 20, and an offset superposed annular supporting portion 23, preferably disposed normal to the flaring wall 2 of the fuel sectionof the producer. Said annular portion 23 of the mantle provides for the erection thereon of said wall 2, in the manner disclosed in Fig. 1,.thereby supporting the entire weight of the shell or fuel containing section, which is thus caused to r0- tate in unison with the ash pan.

By the above described construction, the

1s perfavorable conditions, and the mass of fuel in the producer is caused to be under the continuous influence of the spreading and leveling member 6. A single driving gear for producing the requisite relative rotational' movements between the several parts is all that is required. The distribution of blast to the bed of fuel is rendered most effective by the provision of the equidistant blast arms 16, which, in addition, are ut1- -1ized for the support of the shell or fuel containing section of the producer.

I claim,

1. In gasproducer, a rotating ash pan having an unobstructeda'ash supportlng surface, and a fuel contaaning section carried by said ash pan.

A hollow casting 14:,

In a gas producer, a'fuel section, an ash support below said fuel section and concentric therewith, said ash support having a wholly unobstructed surface from the'center to the periphery thereof, and a member connecting said ash support to said fuel section to constrain their rotation in unison.

said fuel section from said ash pan.

5. In a gas producer, an ash pan, a fuel section above said ash pan, there being con tinuous annular spaces between the wall of said fuel section and the wall and bottomof said ash pan, and means for supporting said fuel section from said ash pan to permit the rotation of said parts in unison.

6. In a gas producer, an ash support having a wholly unobstructed surface from its center to its periphery, a member supported centrally of said ash support, a fuel section carried by said member, and means for imparting rotatlon to one of said parts,-whereby all of said parts will be rotated in unison.

In a gas producer, a rotating ash support,"an annular member supported from the-center of said ash' support, and afuel section carried by said annular member.

8. In a gas producer, a rotating ash support, a plurality of hollow blast arms supported from the center of said ash support and rotatable therewith, and a fuel section carried upon the ends of said blast arms.

9. In a gas producer, a rotatable ash support having a central blast opening, a plurality of hollow blast arms communicating with said opening, and supported at the center of said ash support, and a fuel section carried upon the ends of said blast arms.

10. In a gas producer, a rotating ash support having a wholly unobstructed surface from its center to its periphery, and a fuel section above said ash support and supported fromthe center thereof, wherebysaid parts will rotate in unison.
